Skrillex thinks Taylor Swift's 'Bad Blood' is ''awesome''.

The 27-year-old electronic music producer has praised the star for collaborating with rapper Kendrick Lamar on the single because it shows how artists can ''evolve'', with Taylor previously being known as a country musician.

Speaking about the track, he said: ''I think this is an awesome testament to how artists can evolve. A year ago, you never would have thought that Kendrick Lamar and Taylor Swift would make a song together. I think more things like that are happening, like Jack Ü and Justin Bieber. It's just a fun, catchy song.''

The 'Bangarang' hitmaker - who is one half of Jack Ü along with Diplo - made the comments while discussing some of his favourite tracks of the year, also revealing Fetty Wap's infectious single 'Trap Queen' is his ''anthem of the summer,'' and always plays it during his DJ sets.

He told Rolling Stone magazine: ''This is the anthem of the summer right now. I play this record in almost all of my sets -- I have a bunch of bootleg remixes that I've done, and weird mashups. When that song comes on and you're out, you can't help but sing along.''
